| titleOfInvention | A method for ultrasonic coupling subcritical extraction of potassium in sawdust for stone processing |
| abstract | The invention relates to a method for ultrasonic coupling subcritical extraction of potassium in saw mud for stone processing. The method organically couples ultrasonic treatment and subcritical treatment, which not only improves the leaching rate of effective components, but also effectively removes organic matter in the saw mud. In addition, other impurities are less doped, and at the same time, the present invention is carried out under lower temperature and pressure to avoid destruction of effective cost, and has simple process, short extraction time, low energy consumption, convenient industrial production and good market prospect. |
